-----------------------------------------
Summary: hbase.zookeeper.quorum changing inconsistently on hosts
after adding ZookeeperServer
Key: AMBARI-3954
URL: https://issues.apache.org/jira/browse/AMBARI-3954
Project: Ambari
Issue Type: Bug
Components: client
Affects Versions: 1.4.2
Reporter: Oleg Nechiporenko
Assignee: Oleg Nechiporenko
Fix For: 1.4.2
*Issue 1:*
Steps followed:
*1*. Install a 3-node cluster with Hbase and Zookeeper and 3 zookeeper servers.
*2*. After installation on each host the property
*hbase.zookeeper.quorum* in */etc/hbase/conf/hbase-site.xml* has:
{noformat}
<name>hbase.zookeeper.quorum</name>
<value>c6401.ambari.apache.org,c6402.ambari.apache.org,c6403.ambari.apache.org</value>
{noformat}
*3*. After adding a host with Hbase Region Server, and after that a
ZookeeperServer to it, the property on the added c6404.ambari.apache.org host
has the same value, as in *2*.
*4*. After restarting HBase master on c6401 (which is proposed by UI), the
property value on c6401 becomes:
{noformat}
<name>hbase.zookeeper.quorum</name>
<value>c6401.ambari.apache.org</value>
{noformat}. On other hosts it remains unchanged.
*5.* After restarting HbaseRegionServers on the rest of the hosts (not proposed
by ui), the property changes too, to the same value, as in *4*.

*Issue 2:*
Property *templeton.zookeeper.hosts* in */etc/hcatalog/conf/webhcat-site.xml*
Prior to adding a zookeeperServer on host c6404, config on WebHCat server
lookes like:
{noformat}
[root@c6402 vagrant]# cat /etc/hcatalog/conf/webhcat-site.xml |grep
templeton.zookeeper.hosts -C 2
<configuration>
<property>
<name>templeton.zookeeper.hosts</name>
<value>c6401.ambari.apache.org:2181,c6402.ambari.apache.org:2181,c6403.ambari.apache.org:2181</value>
</property>
{noformat}
After adding a ZookeeperServer on c6404 and restarting WebHCatServer on c6402:
{noformat}
[root@c6402 vagrant]# cat /etc/hcatalog/conf/webhcat-site.xml |grep
templeton.zookeeper.hosts -C 2
</property>
<property>
<name>templeton.zookeeper.hosts</name>
<value>c6401.ambari.apache.org</value>
</property>
{noformat}
*Issue 3*.
On a 3-node cluster with HA-enbaled, property *ha.zookeeper.quorum* in
*/etc/hadoop/conf/core-site.xml*, has the same value on all hosts:
{noformat}
<name>ha.zookeeper.quorum</name>
<value>c6401.ambari.apache.org:2181,c6402.ambari.apache.org:2181,c6403.ambari.apache.org:2181</value>
{noformat}
It doesn't change on either of the hosts after adding c6404 to the cluster,
installing ZookeeperServer on it and restarting HDFS.
